技术领域technical field

Based on this, the traditional method of adjusting the parallelism of the laser lines is to manually use a ruler to measure the distance between the two measured laser lines. The position of the laser line is adjusted. The defect of this adjustment method is that the position information of the laser line cannot be fed back to the operator accurately in real time. The adjustment time of the straightedge method is long, and the parallelism accuracy of the laser line after adjustment is low.
